In response to U.N. Resolution 83, the Norwegian Parliament approved a plan to establish a 60-bed Norwegian Mobile Army Surgical Hospital, or NORMASH, to support U.N. forces in Korea. NORMASH deployed in May 1951 and began frontline operations at Uijeongbu on July 19, 1951. It later relocated farther north to Dongducheon.
The unit operated out of Nissen huts and tents, performing an average of eight surgeries daily. By the end of the war, NORMASH had treated 90,000 patients, including 172 North Korean and Chinese prisoners of war. After the 1953 armistice, the hospital shifted its focus to Korean civilians and served as the sole medical facility for four divisions in the U.S. I Corps sector before returning to Norway in late 1954.
Seven rotational contingents totaling 623 personnel served at NORMASH. Two died in Korea. Driver Arne Christiansen was shot and killed in 1952, and laboratory technician Brit Reisaether died in a car accident in 1954.
For its medical and humanitarian service, the unit twice received the U.S. Meritorious Unit Commendation and the Republic of Korea Presidential Unit Citation.
In 1972, Korean staff gifted a commemorative monument, sculpted by one of their own, and placed it at the site of the Dongducheon facility to honor the partnership. The memorial moved in 2000 to its current location outside the Freedom Protection Peace Museum in Dongducheon, preserving the memory of Norway's wartime contributions.
